See Fig. 6.

V The gear 15 is constantly rotated by a gear 19 secured to the main drive shaft 20 having a belt driven pulley 21 or any other suitable means for operating it. A gear 22 is se cured to shaft and meshes with a gear 23 secured to a transverse shaft 24 jourvnaledon the frame 1 and having-a worm 25 at one end.

` 'Projecting' into one side of the press box so as to be actuated by the compressed materialforming the bale therein, is a. toothed Wheel 26 having a segmental recess 27 one end of which is formed with an Vextension or notch 28. A lug 29 projects into this recess and extends from one end of an arm 30 pivotally connected to a pull bar 31 which, in turn, is pivotally connected to an arm 32 extending downwardly from a pivoted segment 33 fulcrumechas at 34, upon the side of the frame 1 and having a concentric slot near the peripheryV thereof, as'shown at 35. The lower end of the slot is oset as at 36 to form a shoulder 37. A spring 38 connects the pull bar 31 to the frame 1 and exerts a constant pull on the bar so as to hold the parts 3,0, 31 and 32 normally in the positions shown inV Figs. 3 and 4. A hand lever 39 may be connected to the upper portion of the segment 33 by a link 40, as shown.

A stud 41 projects loosely into the slot 35 Vand extends from a block 42 slidably mounted in an L-shaped slot 43 formed in a plate 44 extending from a controlling rod 45. A dog 46 is pivotally'connected to the rod at one end and has a spring 47 for press- Y ing it downwardly yieldingly, said dogheing provided with a beveled end, as shown,

and with a shoulder 48. A spring-49 connects the rod 45 with the frame 1 and serves lnormally to pull the rod upwardly and backwardly away from the wheel 26. A connecting rod 50 is p ivotally attached at one end Vto the dog 18 and has a. stud 51 on its other end which is slidably engaged by one end of the controlling rod 45, there being a. slot 52 inthe rod 45 into which the stud 51 pro- A slot 58 is formed in one end portion of the rod 54 and projecting loosely thereinto is a stud 59 extending from a lever 60. Another stud 61 projects from this lever and into a cam slot 62 formed inthe upper face of a beveled gear 63. The greater portion of the cam slot is concentric with the gear but a short length thereof is extended inwardly toward the center of the gear, as shown at 62. Gear 63 is secured to a vertical shaft 64 j ournaled in bearings at one side of the press box 2, as shown at 65. A beveled gear 66 meshes with gear 63 and is mounted on one end of a'shaft 67, there be- .ing a clutch connection between thisgear and its shaft 67 and which connection, shown at 68, is of the same construction yas the clutch shown at Figs. 6 and 7. In other words a lever 69 is connected to the gear 66 and adapted to engage a recessed disk 70 secured to the shaft 67 so that motion is thus transmitted from the shaft and through the' disk and lever to the gear 66. However, when the lever is tripped, the disk will beV disconnected from the gear and will rotate independently thereof. An ear 71 extends from the restraining rod 54 and is normally underneath the lever 69. `When the rod is v76 at the other side of the press box, it being understood that the rod 74 extends under 105 the press box. Shaft 76 is journaled in upper and lower bearings 77 each of which has a guide sleeve 78. Upper and lower needles 79 are slidably mounted in these sleeves and are iixedly attached to a head 80 at one end 110 thereof. This head, in turn, is connected by a link 81 to a crank arm 82 extending from the shaft 76. See Fig. 9. Each needle has a slot in the end portion thereof, asV shown at 83, there being a pair of grooved rollers in each slot, and which have been indicated at 84.` The needles 79 are provided with depressions 85 close to and back of the slots 83. The two needles are so located that when the plunger or follower 4 is in. its ad- 120 vanced position, they will aline with corresponding grooves 86 formedin the advancing or front lface of the follower and will move transversely of the pressand longitudinally along the grooves. As shown in Fig. 2, these grooves may be provided with hinged guard strips 87 for closing the fronts thereof and preventing straw, etc., from packing back into the groove While the material is beingcompressed. v 13o shaft 64. Located in the frame 88, 89, 90,

Y i above the gear 91 is a pair oftwisting gears described. y K

106 which engage the brackets 108so that,

95 meshing with each .other andthe lower one of which meshes with the gear 91. Another pair of'twisting' gears 96 is located below the gear 91, they being; in mesh with eachother andthe upper gear of the pair meshing with gear 91. All of the twisting gears have radial wire receiving slots 97 extending thereinto and which normally aline with wirevreceiving slots 98 which extend into the plates 88 and 89 from the inner edges. thereof. A retaining pin 99is pivotally mounted in each gear 95and 96 and is adapted to gravitate to positionv across the .inner portion of the slotin the gear, as shown in Fig. 15.

.Brackets 100 extend from 'the plate 88`between the slots 98 of each. pair and groovedwheels 101 are mounted on theseV brackets. A stationary cutting blade 102 is located between each pair of wheels 101. Guide brackets 103 extend romthe plate 88 anda rod 104 is slidably mounted therein and carries cutting blades 105 adapted to coperate with the blades 102 to sever wires, as hereinafter This rod has inclined tongues when the rod is Athrust downwardly, it will be moved inwardly towardl the plate 88 and shear ofi' the wires upon the beveled ends of the xed blades or cutters 102; See F ig. 10. Afcam 107 is provided on the gear'94 for engaging the rod 104V and thrusting it downwardly at the proper time duringthe operation o'l' the apparatus, there being a shoulder 108 von the rod for engagement by the Cam.

The lower end of; the rod 104 bears against one end of a lever 109 and the other endof the .lever is adapted to thrust upwardly against a rod 110 carrying cutters 111 adapted to coperate with xed cutters 112,. TheseA xed cutters are located between slots 98 in V'plate 89, andV a spring 11S on the rod 110,

wardly inclined guard 118. A grooved` wheel 119 isarranged between the linger and its guard and' is normally in a vertical plane.

A'stationary camis located-'in thev path, of each finger, as shown at 120 and isso shaped.

that, .when the finger swings horizontally into position between the side ofthe press-f'y box 2 and the plates 88 and 89 thehead 117 of theiinger will be given a one-quarter turn so asY to bring the wheel of the .finger intoa vhorizontal position with the guard 118 lowermost. While thus Apositioned the finger head 117 Yand the `wheel 119 will' pass over thev Vdepressed portion'85 of a needle 79 `as hereinafter'` described fand engage a wlre 'strand carried by the needle. l*

. Secured `to one side of the frame. 1 between Y the'hopper 3V and the drive mechanism is a Vbraclret 121;v carrying a spool 122 on which the tiewire `W is wound. A slide 128 is mounted on the bracket 121 and is pulled in one direction by an adjustable spring 124.

A grooved lwheel 12,5 is carried by the'slide andengages the wire W ,between the spool 122v and theneedle 79, thus tov hold the wire under` tension. Another bracket 126 supports a spool 127 onthe side ofthepress box 2 between v'the fingers 116 and wheel 26 and aspring drawn'tension wheel 128 isV movably mounted onthe bracket for engaging a wire W extending-trom-the spool 127.

The follower 4 isprovided on one side,

with a tooth or projection 129 adapted'to be engaged by the dog 46 and a lifting pin 130 is extended laterally Jfrom the press box and into the path of the beveled endvoi:l the dog Y force'this material forwardly into the press box in the usual manner. Under ordinary Vconditions the follower is reciprocated uninterruptedly by the shatt 7 driven through the gears 19, 15, 9 and 8. i Shaft 67 is continuously driven by the wormfgearing 25 and 72 but, as the ear 71 is normally posithe material to be,`

tionedunder orinthepath ofthe lever69,

gear 66 isnormally vuncoupled''from the shaft 67 and will., not be. driven thereby.

`Wire W is Iextended from itstension device and-between the wheelsot the needle 79yand thence across the machine through openings 131 in the walls thereof, ysaid wire being `secured to the wire WA extending betweenthe wall ot the press box -and the plates- 88 and 89. As the material is pressed into the press box by the follower it will`push` against that portion of the wire` extending across the press box-and will force itahead ot the material so that thewire will thus lie along three sides of the bale being formed. During this Vmovement of Vthe material it will engage and rotate the wheel 26. During the iii-st half of the rotation of the wheel the recessed portion 27 thereof will allo-wrthe arm 30 to remain stationary but duringy the completion of the rotation of the wheel the stud 29 will become vseated in the notch 28 .and will be pulled by the Wall thereof so as to cause the arm 3() gradually to pull on the bar 31 against the action ofV spring 38. f This willv cause the segment 33 to swing V upwardly rom the position shown in Fig. 3 until the shoulder 37 is brought intoV engagement with the stud 41. Immediately thereafter `the stud 29 will be Y pulled out of thenotch 28 by spring 38 and Y tooth 129 will pullv the dog 46, and rod 45 and cause said rod topull through lthe rod upon the dog 18 which will thus be drawn into the path of lever 12 and/disconnect the shaft 7 from its driving mechanism. This action takes place when the crank 6 arrives at the dead center, thus to hold the follower in its advanced or compressing position. Just as the follower reaches such advanced position the beveled face of the dog 46 is brought against they pin 130 and lifted out of engagement with the tooth 129 so that the spring 49 can return the rod 45 and dog 46 to' their normal positions. Bod 45 is permitted thus to slide back independently h of the rod 54 because'of the slot 52.

l/Vhen rod 50 is actuated by the follower in the manner described it thrusts through rod 54 against the action of spring 57 and shifts the ear 71 from engagementrwith the 'end of lever 69, the slotted end 58 of the rod at the same time sliding on the lever stud 59. 4As soon as :the ear 71 isV thus f moved the gear 66 is coupled to theV shaft 67 and, as said shaft is constantly'rotating, the gear will thus be rotated and will cause gear 63 to rotate therewith in the direction l theportion 62 of groove 62 andallow the spring 57 to return the earl 71 into the path y' of lever 69 and uncouple the gear 66 from 65 7 yshaft 67. f

This sudden and which of course'takes place while the follower 4 is at restV causes the actuation of four separate mechanisms, to wit, the needle mechanism, the threading mechanism, the twisting or tying mechanism, and the wire cutting mechanism. During the lirst half of the rotation of the shaft 64 the crank' 73 transmits motion through rod 74y to "crank 75 which causes the shaft 76 to rotate and,k

swing arm 82. rlhis will pull through link 81 on the head 8O and cause the needles 79 i to slide across the press box, passing into the grooves 86 in the front endl of the follower, the depressions of the needles being brought under the paths of the respective threading fingers 116. During the second half'of the rotation of shaft 64 the needles will be returned to their initial po-V sitions. During the first half of the move' ment of each needle it will bring a loop of its wire 1V across the press box and' within thegroove 86. Meanwhile the crank V73 has been transmitting motion through arv rod 132 to a crank 133 on the lower end of the shaft 114 and the arms 115 swing the lingers 116 over the needles. During the movement of the fingers the heads 117 thereof aregiven a one quarter turn sothat the wheels 119 are brought to horizontal positions and, when the fingers 116 begin their return movement, they will pass over the depressed portions'of the needles and thev wheels 119 will engage the respective tie wires W, drawing them between the plates 88 and 89 and the side of the press bof; and to position back of the plate 89. During this return movement of the fingers 116, which occurs while the needles are being reset, the heads 117 of the fingers turn back to their original positions with Vthe wheels vertical, so that the two strands of each wire loop engaged by a wheel 119 will be drawn laterally into the adjacent pairs of slots 98 and slots 97. The drawing of the strands of wire into the slots in this manner will cause them to press against and lift the pins 99v which ywill subsequently gravitate back to position Y and hold the strands in the slots. from the spool 127 through the slot 97 in the upper gear 95 or 96 and is looped back through the slot 97 in the lower gear of the pair and then extends partly around the bale being formed and is connected to the wire W, it will be apparent that when the wire VJ is threadedy into the slots Y97 in the same gears in which wire W is seated said wires will formopposed loops through the gears as shown in Fig. 14;

During the completionof the threading operation described, the mutilated gears 93 and 94 are brought into mesh vproducing a quick and short movement of the large gear 91` which, in turn, rotates the gears 95 and 96, thereby twisting the wires W and W to- As the wire W extends i or baled, the bending of the strand under the pressure ofthe material thereagainst,v

pressing it back -into the slot in the other gear 95 or 96 thus to forma loop as in Fig. 14 to be connected to the strand W in th manner heretofore described. v

As soon as the shaft 64 completes one revolution, the leverrGO which has-been holding the rod 54 against .returnmovemenu will be released and the rod 54 will thus move to uncouple the gear` 66 as vhereinbefore described. It will also thrust back on the dog 1S and recouple shaft 7 to its drive mechanism so that the follower 4, which had been at rest during the tying operation, can resume its movement to form anew bale. Y

Itisto be understood that a separateset of spools with' wire strands W and W is to be provided for each needle 79.

The lever 39is provided for use when vines, and the like are being baled. lWheel 26 is disconnected and the plunger 4 is permitted to make several strokes after the feeding'of' material to the hopper 3 has stopped. This will cause the long ends to be gathered up and compressed and by then vshifting the lever 39 the parts can be actuated to uncouple the plunger from its driv-` ing mechanism whereupon the balance of the mechanism will operate as hereinbefore described. Y 1Vhat is claimed is l l 1.
